About us

Lo-Rez steel-spring couplings having low torsional stiffness continue to be in demand for difficult applications such as reciprocating gas compressor drive systems, where unacceptably high stresses can occur in either the compressor crankshaft or driving rotor shafts.

Lo-Rez supplies steel-spring couplings rated from a few hundred to many thousands of horsepower such as the one shown below, destined for hydrogen compression service at a refinery in South-East Asia. Ted Spaetgens

Canadian Coast Guard 47-foot lifeboats 31 vessels built to date utilize BR4-ELS isolators to support the twin Caterpillar propulsion engines.The BR4-ELS isolators were selected for this job because of their excellent vibration and noise attenuation ...

Three Washington State Ferries Mark II Jumbo Ferries supplied with Lo-Rez BR4-HS isolators supporting the four EMD 16V710 gensets, (110,000 lbs.) used for producing propulsion and house power for the entire vessel.

With the higher rotative speeds of modern machines, it is only rarely necessary to provide more than 2 inches of static deflection in undamped vibration isolators. The vertical (theoretical) natural frequency, 133 cpm (165 modified) – correspo...
